FIQEO WILLIAM J. GRINDEN, OF BROOKLYN, NEW YORK..

METAL BARREL.

Specification of Letters Patent.

Patented Aug. 22, 11916.

Application filed November 20, 1915. Serial No. 62,572.

To all whom it may concern: Be it known that I, WILLIAM J. GRINnEN, acitizen of the United States of Amerlca,

and residing in the borough of Brooklyn,

in the county .of Kings and State of New York, have invented a certainnew and Improved Metal Barrel, of which the following is aspecification.

My invention relates to metal barrels and particularly to the endclosures therefor, the object of my invention being to provide a readilyapplied rigid end closure for a metal barre In the accompanyingdrawing,Figure 1 is a vertical section through a barrel in which my, inventionis illustratively embodied; Fig. 2 is a horizontal section therethrough;Fig. 3 is a detachedbroken perspective of portion of the barrel; andFig. 4 is a broken perspective of a detail.

In the form here shown, the present barrel is of the knock-down type andcomprises two sheet metalsections 10 and 11, each curved tosemi-cylindrical shape and having its longitudinal margins outwardlyrecurved to form in the assembled barrel oppositelyfaced flanges 12-and13 exterior to the barrel at the joint 14 between the body sections. Akey 15, also formed from sheet metal, has recurved marginal flanges 16and 17 which enter the grooves formed by the flanges 12 and 13 andrigidly tie the barrel sections together throughout the length of thebody of the barrel. Adjacent each end of the barrel the sections 10 and11 are peripherally grooved in register at 18 and 19 to afford Vsubstantially flat internal ledges or seats for the respective endclosures 20 and 21. As

shown, these end closures comprise wooden heads 20 and 21 which restupon the said ledges and are of a thickness substantially correspondingto the portions 22, 23, of the barrel body which extend beyond thegrooves 18. and 19. To firmly secure these heads to their seats, Iemploy for each a split, chan- Bel-section, locking ring 24, theflange25 of which in assembled position overlies the outer margin of theclosure head whilethe inner flange 26 enters the groove 18 or 19' formedin the body of the barrel. After the locking ring has been adjusted inposition as shown in Fig. 1, it is fastened by means of nails driventhrough perforations 2:7 and 28, adjacent the ends of the split ring.These nails pierce the portions 22 and 23 of the barrel body and enterthe wooden closure heads 20 and 21 substantially at right-angles to theaxis of the barrel, thus holding the channel ring in position andthereby securely fastening the heads. While this assembly of parts isvery rigid, the barrel may be still further reinforced by making the endflanges 27 and 28 of the keys 15 of such length that they may beextended beyond the ends of the'barrel and bent over and secured to theheads 20 and 21 by means of nails driven through the flanges. This givesa more or less rough finish however, and it is preferable to make theflanges 27 and 28 shorter and insert them in the grooves 18 and 19 wherethey are concealed and protected.

The structure not only affords a very strong barrel which will containheavy substances, such as cement, without breakage, even on roughhandling, but it also presents the great advantage that it may beshipped in knock-down form with the barrel sections 10 and 11 nested andthe remaining parts of the barrel stacked. This is not only true of theoriginal shipment to the user of the barrel, but it also applies to areturn shipment of the barrel after use, since the only parts apt to beinjured on the opening of the barrel are the heads 20 or the lockingrings 24 and. keys 15 and these may be readily replaced.

Various modifications in detail of construction will readily occur tothose skilled in the art without departing from what I claim asmyinvention, and I do not limit myself to the precise form shown.

I claim as my invention A sheet metal barrel having its wall inwardlygrooved adjacent the end of the barrel to form a substantially flatinternal ledge, a. wooden head restingupon said ledge and an externalsplit locking ring of channelsection having a pair of uninterrupted Intestimony whereof I have signed my annular flanges one flange overlyingthe name to this specification, in the presence of outer face of thehead and its other flange two subscribing Witnesses.

ring in position to retain said head. L. H. GRoTE.
